Comparative Study
A Tuberculosis Antigen-stimulated CXCR3 Ligand Assay for the Diagnosis of Active Pulmonary Tuberculosis.
The ligands for CXC chemokine receptor 3 (CXCR3) recruit T-helper type 1 cells, which play a major role in cell-mediated immunity in TB. ⋯ TB antigen-stimulated assays of I-TAC and MIG may be useful surrogate markers in the diagnosis of active pulmonary TB.

Lung ultrasonography is useful for the diagnosis of pneumonia in children and adults. This study investigated the lung ultrasound findings in severe neonatal pneumonia. ⋯ Lung ultrasonography is a reliable tool for diagnosing neonatal pneumonia. It is suitable for routine use in the neonatal ICU and may eventually replace chest radiography and CT scanning.

Local anesthetic (medical) thoracoscopy is used with increasing frequency by pulmonologists worldwide for both diagnostic and therapeutic purposes, notably in comorbid patients who may not be physiologically robust enough for general anesthesia. Understanding the complications that can arise and how to manage them is crucial for any physician performing this procedure. ⋯ This case provides an opportunity for an overview of what is known about this unusual but potentially fatal condition. Data correlating ultrasonographic, radiographic, and clinical progression are also presented to highlight the potential usefulness of ultrasonography in identifying lung parenchymal abnormalities such as extravascular lung water.
